Problems solved by technology

[0008] Therefore, according to the conventional retroreflective sheeting, a small amount of light is reflected in the colored region other than the reflective region, so there is a problem that the reflected light is less bright and the visibility is lowered.

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0025] figure 1 is a plan view of a retroreflective sheeting according to an embodiment of the present invention, figure 2 will be figure 1 Sectional view cut along line A-A.

[0026] In the case of the retroreflective sheeting according to the present invention, the reflective portions 43 are formed on the colored portion 26 at regular intervals and laminated in a stripe shape. Thus, the region where the reflective portion 43 is laminated defines the reflective region L2, and the region where the reflective portion 43 is not laminated becomes the colored region L1.

[0027] The colored part 26 includes a heat-resistant film 41 , a first thermoplastic adhesive layer 23 , a first flame-retardant layer 21 , a colored layer 19 , a light-transmitting layer 17 and a first light-collecting layer 15 .

[0028] The heat-resistant film 41 prevents the first thermoplastic adhesiv...

Abstract

The present invention relates to a retro-reflection sheet and a manufacturing method thereof. The retro-reflection sheet comprises: a colored portion that emit light to the outside through a heat-resistant film, a first thermoplastic adhesive layer, a first flame-retardant layer, a colored layer, a light-transmissive layer, and a first light-collecting layer; and a reflective portion that cause reflection of light incident on a reflective region through the second thermoplastic adhesive layer, a second flame-retardant layer, a reflective layer, and the second light-collecting layer.

Description

technical field [0001] The present invention relates to a retroreflective sheet and fabricating method thereof, in particular, to a retroreflective body and a manufacturing method thereof, the retroreflective body can improve the light reflection efficiency of colored areas at night, Thereby, visibility (visibility) is improved. Background technique [0002] A retroreflective sheet is a reflector that includes a light collecting layer and a reflective layer and allows incident light to be directly reflected along the incident direction. Retroreflective sheeting is usually formed in the form of a plate, and is processed into a desired shape or pattern on the main surface of the attached object, and is selected by attaching to road sign boards or uniforms of firefighters by means of thermocompression bonding or tailoring. part, thereby improving the visibility (visibility), and even in the dark place of the surrounding environment, it is easy to be displayed. Therefore, if t...
